【问题描述】：

我创建了一个名为 popuplistfragment.java 和 list_view.xml 的列表视图。我在 xml 文件中添加了 textview，但我不知道在哪里添加代码来更改列表视图中的 textview。

import android.app.ListFragment;
import android.content.Intent;
import android.os.Bundle;

import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import android.widget.Toast;

public class PopupListFragment extends ListFragment implements      OnItemClickListener 

TextView textview;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,  Bundle savedInstanceState) 
    View view = inflater.inflate(R.layout.list_item, container, false);
    return view;


@Override
public void onActivityCreated(Bundle savedInstanceState) 
    super.onActivityCreated(savedInstanceState);

    ArrayAdapter adapter = ArrayAdapter.createFromResource(getActivity(),  R.array.quotes, android.R.layout.simple_list_item_1);

    setListAdapter(adapter);
    getListView().setOnItemClickListener(this);


@Override
public void onItemClick(AdapterView<?> parent, View view, int position,long id) 
    //Toast.makeText(getActivity(), "Item: " + position, Toast.LENGTH_SHORT).show();
    String item = (String) parent.getItemAtPosition(position);
    Log.v("check", "item is clicked");


    Intent myIntent = new Intent(getActivity(), SwipeViews.class);
    myIntent.putExtra("key", item);
    myIntent.putExtra("index", position);
    startActivity(myIntent);

这是 list_view.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_
android:layout_
android:background="@drawable/back_listview">
<ListView
    android:id="@android:id/list"
    android:layout_
    android:layout_
    android:longClickable="false"

    >
</ListView>

<TextView
    android:id="@+id/text1"
    android:textColor="#e15258"
    android:layout_
    android:layout_
    android:layout_weight="1"
    android:gravity="center_vertical"
    android:paddingLeft="8dp"
    android:paddingRight="8dp"
    android:maxLines="1"
    android:ellipsize="end"
    android:textAppearance="?android:attr/textAppearanceMedium" />

</LinearLayout>

【参考方案1】：

首先你需要扩展适配器类

public class ListAdapter extends ArrayAdapter<String> 
   String [] mQuotes;
   public ListAdapter(String [] quotes)
      mQuotes = quotes;
   
   public View getView(int position, View convertView, ViewGroup parent) 
       View v = convertView;
       if (v == null) 
           LayoutInflater layoutInflater = LayoutInflater.from(getContext());
           v = layoutInflater.inflate(R.layout.itemlistrow, null);
       
       TextView quoteTextView = v.findViewById(R.id.quote_textView);
       quoteTextView.setText(mQuotes[position])
       return v;
   

   @Override
      public int getCount() 
         return quotes.length;
      

然后实现其他方法。 下一步是更改下一个代码

@Override
public void onActivityCreated(Bundle savedInstanceState) 
    super.onActivityCreated(savedInstanceState);
    String [] QuoteArray = getResources().getStringArray(R.array.quotes);
    ListAdapter adapter = new ListAdapter(QuoteArray);

    setListAdapter(adapter);
    getListView().setOnItemClickListener(this);

然后将 itemlistrow.xml 添加到 Layout 文件夹并进行更改：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="horizontal"
          android:layout_
          android:layout_>

   <TextView
       android:id="@+id/quote_textView"
       android:layout_
       android:layout_/>

</LinearLayout>

您可以根据需要自定义 itemlistrow.xml
